3718T COBRA Streetrod FULL SYSTEM M50 C50 all models Great sound with classic Streetrod style. These Streetrods use large 2.5-inch, 222o heat shields that cover from the exhaust ports to the chromed billet tips for a seamless look and non-bluing finish. The chromed billet end caps are beautifully machined for show-custom look. These pipes give an overall power increase with improved rideability (made even better with the installation of the Cobra Fi2000 fuel processor). As always with Cobra exhausts, they are easy to mount and come with all mounting hardware needed for a professional installation.
